To all whom it may concern/.-

Be it known that I, VARREN MCARTHUR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tubular Lanterns, of which the following is a specification.

This invention relates to an improvement in that class of tubular lanterns which are 1o provided with a globe-frame capable of being moved up and down in the tubular frame by means of a lever, which is pivoted to the base of the lantern-frame and attached with its inner arm to the lower part of the globe-frame, so that upon depressing the outer arm of the lever the lower part of the globe-frame will swing` upwardly and rearwardly from the burner.

The objectof my invention is to provide simzo ple means for locking the globe-frame down in its normal position upon the burner.

In the accompanying drawings, consisting of two sheets, Figure l represents a rear elevation of a tubular lantern provided with my improvements. Fig. 2 is a side elevation therev of, partly in section. Fig. 3 is a horizontal section in line af x, Fig. l. Fig. 4 is a side ele vation, partly in section, showing the globe and its support tilted. Fig. 5 is a similar elevation showing the globe-frame lifted from the burner. Fig. 6 is a similar elevation showing` a mcdilied construction of my invention.

Like letters of reference refer to like parts in the several figures.

A represents the oil-pot, ct the air-chamber secured to the top of the oil-pot, and B the burner surmounting the air-chamber.

C C represent the side tubes secured with their lower branches to the top of the oil-pot 4o and connected with their upper branches to the central depending tube c.

D is the bell or air-gatherin g plate, mounted on the central tube c so as to be capable of vertical movement thereon.

E represents the lift Vwires or rods secured with their upper ends to the bell D and attached with their lower ends to the globe-supporting plate c in such manner that the latter can be tilted. This connection is preferably eilected by hooks formed at the lower endsof the lift-wires and eyes formed on the globeplate.

F represents the globe resting upon the plate c, and G represents the globe-spring, which is attached to the bell and holds the upper end of the globe removably in place. Any other globe-fastening which permits the globe to be released may be employed in place of the globe-spring, if preferred. The bell D, lift-wires E, an d plate c form the globe-frame, which is capable of movement up and down in the lantern-f rame toward and from the burner.

II represents the lever by which the globeframe is raised from the burner. This lever is constructed in the form of an inverted-U- shaped frame, and is pivoted to a standard I, which is secured to the oil-pot on the rear side of the lantern. This standard is provided with a horizontal top-bar 1f, on which the two branches of the lifting-lever turn. The lower branches 7L of the lifting-'lever are arranged horizontally underneath the globe-plate e, and the bow-shaped portion 7L of the lever extends upwardly from the standard on the rear side of the globe and forms the rear guard.

J represents the front guard, composed of an inverted-Ushaped frame similar in form to the lifting-lever H, and secured with its lower horizontal portions to the under side ot' the globe-plate e, so that the latter and the front guard tilt together. The ends of the front guard are provided with eyesj, in which engage outwardly-proj ectin g pivots lo, formed on the ends of the lifting-lever, whereby the latter is connected with the globe-supporting plate e.

L represents a springecatch which is secured to the bell and extends downwardly therefrom to the upper end of the lifting-lever and locks the same in its normal position, in which the globe-frame rests upon the burner. As shown in the drawings, this catch is made of wire and provided near its lower end with a shoulder Z, which engages under the bow of the lifting-lever and prevents the upper end of the latter from swinging outwardly, thereby locking the globe-frame in its normal position.

An y other catch which prevents the upper end ot the lifting-lever from swinging outward will answer the same purpose-for instance, a hook M connecting the upper end of the lifting-lever with the upper end of the front guard.

I do not claim a guard arranged on one side ot' the globe and secured to the globe-frame, or a lifting-lever forming a guard on the opposite side of the globe.

l claim as my invention-- l. The combination, with the tubular lantern-frame and the globe-frame capable of moving up and down in the tubular frame, of a lifting-lever pivoted to the base of the tubular frame and havin one arm connected with the lower portion of the globe-frame, and a catch attached to the movable globe-frame and engaging with the other arm of the lifting-lever, whereby the lifting-lever is locked to the movable globe-frame, substantially as set forth.

2. The combination, with the tubular lan tern-frame provided with a depending central tube, of a bell capable of vertical movement on said tube, a globe-Supporting plate, lift- Wires connecting said plate with the bell, a lifting-lever pivoted to the base of the tubular frame and having its upper arm projecting upwardly along the globe, and a catch secured to the bell and extending downwardly to the lifting-lever, substantially as set forth.
